Q: What determines the brightness of the patch LED?: The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.

Q: What is patch SMD-LED?: Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.

Q: Is the forward voltage drop of the patch LED too large or too small?: Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you

Q: Patch LED light does not flash, why?: Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.

Q: Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?: LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications

Q: How many volts is a single LED on the LED patch band?: LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.

Q: What are the storage requirements of SMT patch LED (LED)?: Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours? remove the pouch before baking, and do not open the oven door frequently

Q: What does "1210" mean in patch LED?: At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.

Q: SMD LED lamp working voltage?: 18 volts driven high 3030LED lamp (six core series, and 2 core, 3 core series and Design), driving power of up to 1W,1W high voltage 3030 LED (3 volts, 6 volts, 9 volts, 18 volts optional)

Q: Such as title, please have welding patch LED lamp experience expert guidance, do not search from the Internet to the theoretical knowledge, thank you!: First of all, welding LED and other electronic products with line electrostatic ring, to prevent static light.When welding the patch LED lamp, first add the tin on the pad of the lamp board, then clamp the LED patch lamp with tweezers. Then, the soldering iron will melt the tin of the solder plate of your lamp board, and then push the LED lamp onto the pad with tweezers. The whole welding process should not exceed 5 seconds, otherwise it will burn the lamp easily.
